I am using Exim but the problem has gone away now. I did notice that this
server (a Leaseweb VPS, formerly Servint) was briefly on the UCEPROTECT3
about that time. I can't believe that Gmail would use that list for scoring

Are you running exim?
I have the following in my config, which seems to help the issue:
# disable TCP fast open for gsmtp servers, due to a kernel bug; the bug was
supposedly
# fixed in 5.18, but it seems there's still some quirkiness with gmail
without this
# setting

ordinary notification from nytimes.com. The second looks like similar from
foodandwine.com.
